ladder efficiency

Hi:
  Somewhat new to PLCs and can't seem to "20 question" an anwer to the following:
   I've heard or read that a rung will be evaluated only to the first false
argument at which point the next rung is begun.  This would give much opportunity for improving the speed and shortening the scan time.
  Is the above true?
